Composite decking is strong. It needs little care. But even this material fades over time. Sunlight, rain, and dirt slowly break down the surface. If you don’t act, the fading gets worse. Water may collect beneath the boards. UV rays keep wearing away the top layer.
This guide explains what causes fading, how to fix it, and how to stop it from returning.
Why Composite Decking Fades
Composite decking is made to last. Still, the surface changes as it gets older.
Sunlight is a major reason. UV rays hit the boards and break down the material. Decks in full sun fade faster than shaded ones.
Weather is another cause. Heavy rain and strong wind can weaken the surface. Sudden changes in temperature make things worse. If boards are not sealed, water can get in and speed up damage.
Air pollution can add to the problem. Dust, dirt, and chemical particles settle on the boards. Over time, this buildup wears away the finish.
How to Restore Faded Composite Decking
Faded boards can look new again. Use the right steps to restore the colour and protect the surface.
1. Clean the Surface
Start with a deep clean. Use water and mild soap. Scrub with a soft brush. Wash off dirt, stains, and mould. Cleaning well makes the next steps work better.
2. Use a Restoration Product
Let the surface dry. Then apply a colour restorer made for composite decks. This product brings back colour and adds protection. Follow the label instructions. Some products need two coats.
3. Use a Power Washer Carefully
A pressure washer helps remove deep stains. But be careful. High pressure can damage the surface. Use a low setting. Hold the nozzle at an angle. Keep your distance while spraying.
4. Apply a Sealer
When the colour is restored, seal the surface. A sealer blocks moisture. It also guards against UV rays. Some sealers improve grip and reduce slipping.
5. Replace Badly Faded Boards
If a board is too worn, replace it. It’s better to swap a few than let the whole deck look patchy or old.
How to Prevent Fading
Keep your deck clean. Sweep away leaves and rinse off mud. Remove puddles before they soak in.
Avoid harsh cleaners. Don’t use bleach, acid, or rough tools. These can strip the finish. Choose cleaning products made for composite decking. They are safer and work better.
Clean often. Use a broom or soft mop. After washing, rinse with water. Make sure no soap is left behind.
Use a sealer or protectant once or twice a year. Pick one with UV blockers. This helps slow down sun damage.
Add shade if possible. Use an umbrella, pergola, or tall plants. Less sun means less fading.
Using a Composite Deck Restoration Kit
If fading is clear, try a full restoration kit. Most kits come with cleaner, restorer, and protectant. Some also include tools like brushes or rollers.
Clean the surface first. Let it dry. Then apply the colour restorer. Finish with the protectant layer.
Choose a kit that matches your deck’s colour. Some let you adjust the tone with tints or shades.
Keeping Your Deck in Good Shape
Daily habits help a lot.
Wipe up spills fast. Clean grease and bird droppings before they soak in. Use pads under tables and chairs to prevent scratches. Move furniture once in a while. This helps avoid uneven fading.
Trim plants near the deck. Branches and leaves drop debris. They also block airflow. Keep the area open to help the surface dry faster.
Make cleaning a regular task. Sweep once a week. Rinse off dirt when needed. Add a new coat of protectant every six months. Small tasks make a big difference over time.ompotech Decking can provide a pleasant, warm, and environmentally responsible outdoor living place.
